Look Up Table (LUT) for gray level images

Is there currently an option in the image viewer to use a colorful LUT for gray level images ?
This could be useful for heatmap visualisation…

I tried the Table Color based image renderer option but it returns
WARN Real2TableColorRenderer Unsupported color table format. Using linear grey ramp.

Thanks

This renderer is meant for images that already contain a LUT when read in. As far as I know there no ways to directly create ColorTables using KNIME Image Processing nodes. You might be able to using the Java Snippet node and some Imglib2 code, I could look into that if you are interested in such an option.
best,

Hi Gabriel,
Thanks fro the answer,
If you have a simple hack with python nodes eventually, otherwise dont worry with that, It would be a nice to have in the future :wink:
